Hi Lars,
I assume that cmd.exe inherits its bahavior from msvcrt.dll, hence I
expect that C programs which are using the fopen() function defined in
msvcrt.dll don't support UNC paths either.

BTW, the source code of msvcrt.dll looks quite DOSish and has not
been changed for decades.  It obviously predates UNC paths.
